Probability of selecting an ace or 7

Step-by-step explanation:

Since it the question asks for Ace OR 7

Taking a deck of cards which has 52

we will need to find all the Ace's and Seven's

in the photo below i added a picture to represent for you!

So we have 8

now find how many outcomes there are.

which is 52

what we want

-------------------

total number of outcomes

~~~~~~~

 0.8              

---------      =  1.538461538461538

0.52

now were gonna round which is gonna be 1.5

(theres not enough details for me to do it correctly please use this as a guide or use it i dont know if it will be correct though.)

Hope this helps you

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
